Combine sugar, cinnamon, and salt on a small, flat plate. Pour a small amount of maple syrup on another small plate. Dip the rim of the glass in a bit of maple syrup.
Next, dip the glasses into the sugar and salt mixture and fill the glass halfway with ice.
Add all of the ingredients to a cocktail shaker filled with ice.
Shake well for at least 10 seconds. Strain the pumpkin spice margarita mixture into the glass and enjoy!
